Dummy Output

Bonjour,

je suis nouveau sur Debian, et je n’y connais pas encore grand chose, et c’est pour cela que je vais sur ce forum pour régler un problème qui est que le son ne marche pas, et le système me marque « Dummy Output » en tant que sortie audio. Pouvez-vous m’aider s’il vous plaît ?

Merci d’avance pour votre réponse !

salut
il te manque probablement un paquet
en général tu trouves la réponse dans un fichier de log;
tu peux essayer
sudo dmesg |egrep -i "firmware|error"

explication :
sudo : faire uen commande en root ( superutilisateur )
dmesg : la commande dmesg marque les messages du système
| : « tube » : prend la sortie ( l’affichage de sudo dmeg qui contient des centaines de ligne et l’envoie vers la suite de la ligne )
egrep -i : regarde les caractères de chaque ligne ; -i : indépendamment de la casse ; -e regex ( permet d’interpréter le | suivant comme un OU logique )
« firmware|error » : le mot firmware ou le mot error ( sans le e de egrep, la recherche se ferait sur le mot entier firmware|error

voir là aussi :

vérifier l’existence du programme de son :
ps aux |egrep "pipewire|pulse" |grep -v grep doit afficher /usr/bin/pipewire et /usr/bin/pipewire-pulse

user       2152  0.6  0.1  96920 37984 ?        S<sl 19:35   1:12 /usr/bin/pipewire
user       2154  0.7  0.1 103980 52444 ?        S<Lsl 19:35   1:33 /usr/bin/pipewire-pulse

Sinon, installer pipewire pipewire-bin et pipewire-pulse : apt-get install pipewire pipewire-bin pipewire-pulse

salut, et merci pour ta réponse !

J’ai effectué la première commande que tu m’a fournie, et voici le résultat :

Et pour la deuxième commande, j’ai bien le résultat attendu

je ne vois pas de truc à faire ;
tu peux essayer ça :

SOLUTION 1 ( peut être ): installer pleins de pilotes
selon que tu es sous bookworm ou autres, aller voir sur ces pages

et installer les pilotes(drivers) puis redémarrer

ou :

mais bon c’est un peu bourrin

recherche 1
installe qjackctl et lance le en ligne de commande : y-a-t-il un message qui apparaît dans la ligne de commande?

recherche 2

recherche 3

premièrement, j’ai effectué la commande qjackctl -s pour lancer directement depuis le terminal et voici ce qui apparais dans une nouvelle fenêtre :

ensuite, j’ai fait la deuxième commande proposée et ça m’a donné ça :

$ cat /proc/asound/timers

Et concernant la troisième commande, voici la réponse :
